Splitter Televes AZ414D 4-way 14 dB, frequency 5–1218 MHz

Televes AZ414D 4-way 14 dB splitter is a passive RF distribution device designed to divide a single coaxial input into four outputs while preserving impedance matching and limiting signal degradation across a wide frequency band. Covering 5–1218 MHz, it supports terrestrial TV, antenna systems and intermediate stages in small distribution networks where consistent signal levels and isolation between outputs are required.

Advantages

The splitter provides 14 dB isolation between outputs to reduce cross-talk and prevent interference from connected branches. Its frequency range from 5 to 1218 MHz makes it compatible with VHF/UHF and many cable TV frequency plans. The unit is passive and requires no power supply, ensuring simple installation and low maintenance. Built with impedance-matched connectors and a robust housing, the device helps maintain signal integrity and stable performance in typical residential and small commercial installations.

Suitable for

• Home and apartment antenna signal distribution to multiple receivers
• Small multiswitch or distribution hubs in private installations
• Replacement or expansion of existing TV coaxial split networks
• Signal splitting in setups that require moderate output isolation and broad frequency coverage

Key specifications

• Number of outputs: 4
• Isolation between outputs: 14 dB
• Frequency range: 5–1218 MHz
• Impedance: 75 Ω
• Type: Passive RF splitter
• Connector type: coaxial F-type compatible

How to use

Connect the incoming coaxial cable carrying the antenna or cable signal to the splitter input, and attach each output to the coaxial runs leading to receivers or further distribution devices. Ensure all connections are tightened and use quality coaxial cables to reduce insertion loss. Install the splitter in a sheltered, dry location away from strong electrical interference and avoid excessive bending of cables at the connector interfaces. Because the device is passive, no power connection is necessary.

Usage recommendations

For optimal performance, place the splitter near the signal source to minimize cable length on the input side, and use low-loss coaxial cable (75 Ω) for runs to receivers. If signal levels are low after splitting, consider using an amplifier or a distribution amplifier upstream of the splitter rather than cascading multiple passive splitters. Verify system impedance and ensure connectors are corrosion-free for long-term reliability.
